Description

Indication method for physical channel repeat transmission and equipment/storage medium/device

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a method, device, storage medium, and apparatus for indicating physical channel repeat transmission.

Background

In NR (New Radio) systems, in order to enhance signal coverage, repeated transmission is introduced.

In the related art, for a PDSCH (Physical Downlink Shared Channel), only transmission of the same time domain symbol on consecutive time slots is supported; for PUSCH (Physical Uplink Shared Channel), the following two retransmission schemes are supported:

type A: the PUSCH is repeatedly transmitted on the same time domain symbol in each continuous time slot;

type B: the PUSCH may be based on a mini-slot (small slot) repetition transmission, which may cross slot boundaries.

In the process of repeated transmission, transmission may need to be terminated in advance, where for PUSCH repeated transmission, when DCI (Downlink Control Information) scheduling of the same process is received, the DCI indicates new data, and at this time, HARQ-ACK (Hybrid Automatic Repeat request-acknowledgement character) feedback of the uplink process is implicitly indicated to be ACK, and then subsequent repeated transmission does not need to be performed.

However, in the related art, continuous time slots are used for retransmission, and time domain channel differences in NTN (Non-Terrestrial Networks) may not be matched, resulting in poor communication quality. And, for the case of early termination of transmission, in the NTN, because RTT (Round Trip Time ) is too large, when the base station finds that transmission can be terminated and sends DCI to the UE after receiving partial retransmission, the UE receives DCI scheduling of the same process, and when the DCI indicates new data, retransmission may have been completed all times, thereby causing waste of resources.

Fig. 1a is a schematic flowchart of an indication method for physical channel repeat transmission provided in an embodiment of the present disclosure, which is applied to a UE, and as shown in fig. 1a, the indication method for physical channel repeat transmission may include the following steps:

and step 101a, receiving configuration information which is sent by the network equipment and used for repeated transmission.

It should be noted that in one embodiment of the present disclosure, a UE may refer to a device that provides voice and/or data connectivity to a user. The terminal device may communicate with one or more core networks via a RAN (Radio Access Network), and the UE may be an internet of things terminal, such as a sensor device, a mobile phone (or referred to as a "cellular" phone), and a computer having the internet of things terminal, and may be a fixed, portable, pocket, handheld, computer-included, or vehicle-mounted device, for example.

Alternatively, the UE may also be a device of an unmanned aerial vehicle. Or, the UE may also be a vehicle-mounted device, for example, a vehicle computer with a wireless communication function, or a wireless terminal externally connected to the vehicle computer. Alternatively, the UE may be a roadside device, for example, a street lamp, a signal lamp or other roadside device with a wireless communication function.

In one embodiment of the present disclosure, the present embodiment may be applied to an NTN system.

In an embodiment of the present disclosure, the physical channel repeated transmission may include at least one of the following:

repeated transmission of PUSCH;

repeated transmission of PDSCH;

repeated transmission of a PUCCH (Physical Uplink Control Channel);

a Physical Downlink Control Channel (PDCCH) repeat transmission.

And, in an embodiment of the present disclosure, the configuration information may include a transmission resource specifically used for the repeated transmission and/or indication information, and the indication information may be used for indicating the transmission resource of the repeated transmission of the physical channel. And the transmission resource is non-contiguous in time. The transmission resource may specifically include at least one of the following:

the total number of repeated transmissions; wherein, the total number of the repeated transmission can be the total number of the transmission time;

the time interval between each repeated transmission opportunity;

the number of retransmissions transmitted at each retransmission opportunity;

repeated transmission pattern information (which may be used to determine the time interval described above and/or the number of repeated transmissions transmitted per repeated transmission opportunity).

It should be noted that, in an embodiment of the present disclosure, the transmission resources may be predetermined by the network device according to the RTT and/or the current channel quality, so that the interval between the determined transmission resources may be matched with the RTT, thereby avoiding occurrence of a situation that "when the UE receives the information for terminating the retransmission, which is sent by the network device, due to retransmission performed by using the continuous transmission opportunity, the UE has completed all the repeated transmissions", thereby reducing useless transmission and saving power consumption.

In addition, in an embodiment of the present disclosure, when the content in the configuration information is different, a method of receiving the configuration information sent by the network device in this step may also be different, and details about this part of the embodiment will be described later.

Step 102a, determining transmission resources for repeated transmission according to the configuration information.

In an embodiment of the present disclosure, the transmission resource for repeated transmission determined in this step may include, for example: a total number of repeated transmissions, a time interval between each repeated transmission opportunity, a number of repeated transmissions transmitted per repeated transmission opportunity. When the number of repeated transmissions transmitted per repeated transmission occasion is not indicated, the UE may adopt a default value, which may be, but is not limited to, 1, i.e., the number of repeated transmissions transmitted per repeated transmission occasion is 1.

Further, in another embodiment of the present disclosure, the transmission resource determined in this step for repeated transmission may include, for example: a total number of repeated transmissions, repeated transmission pattern information that may be used to indicate at least a time interval between each repeated transmission opportunity and/or a number of repeated transmissions transmitted per repeated transmission opportunity in a repeated transmission process. And fig. 1b is a schematic structural diagram of repeated transmission pattern information provided in the embodiment of the present disclosure. Referring to fig. 1b, the retransmission process indicated by the retransmission pattern information includes two retransmission occasions, namely a first retransmission occasion and a second retransmission occasion, and the retransmission pattern information further indicates that the number of retransmissions transmitted at each retransmission occasion is 2.

And, the total number of the above repeated transmissions may be configured to the UE by the network device, and the "time interval between each repeated transmission opportunity, the number of repeated transmissions transmitted at each repeated transmission opportunity, and the repeated transmission pattern information" may be configured to the UE by the network device, or may be determined by the UE based on predefined information, which will be described in detail in the following embodiments.

Step 103a, determining the repeated transmission opportunity according to the transmission resource.

In an embodiment of the present disclosure, when the transmission resources determined by the UE in step 102a are different, the method for determining the repeated transmission opportunity may also be different.

Specifically, in an embodiment of the present disclosure, when the transmission resource determined based on step 102a includes: the UE may determine the retransmission timing according to the transmission resource when the total number of retransmissions, the time interval between each retransmission timing, and the number of retransmissions transmitted at each retransmission timing is: the UE determines a first retransmission opportunity (for example, the UE may determine a receiving time point of indication information indicating that the UE starts to perform retransmission, which is sent by the network device, as the first retransmission opportunity), and then determines each retransmission opportunity of the UE based on the first retransmission opportunity, a time interval between each retransmission opportunity, and a total number of retransmission opportunities.

For example, in an embodiment of the present disclosure, fig. 1c is a schematic structural diagram of a retransmission opportunity determined based on a time interval between each retransmission opportunity provided by an embodiment of the present disclosure. Assume that step 102a determines that the transmission resources for the repeated transmission are: if the total number of times of the repetitive transmission is 4 and the time interval between each repetitive transmission opportunity is 10ms, as shown in fig. 1c, the UE determines the first repetitive transmission opportunity, may determine an opportunity 10ms apart from the first repetitive transmission opportunity as the second repetitive transmission opportunity, may determine an opportunity 10ms apart from the second repetitive transmission opportunity as the third repetitive transmission opportunity, and may determine an opportunity 10ms apart from the third repetitive transmission opportunity as the fourth repetitive transmission opportunity, thereby determining each repetitive transmission opportunity.

And, in another embodiment of the present disclosure, when determining the transmission resource for the repeated transmission based on step 102a includes: when the pattern information is repeatedly transmitted, each repeated transmission timing can be directly determined according to the repeated transmission pattern information (the repeated transmission pattern information shown in fig. 1 b).

In summary, in the indication method for physical channel repeat transmission provided in the embodiment of the present disclosure, the UE may receive configuration information for repeat transmission sent by the network device, determine a transmission resource for repeat transmission according to the configuration information, where the transmission resource is discontinuous in time, and determine a repeat transmission timing according to the transmission resource. Therefore, in the embodiment of the present disclosure, the UE may perform repeated transmission by using a discontinuous transmission resource, that is, each transmission opportunity has a time interval, and based on this, after the UE performs retransmission at a certain transmission opportunity in the NTN system, if the network device finds that transmission can be terminated and sends information for terminating retransmission to the UE, the UE may not reach the next transmission opportunity when receiving the information for terminating retransmission, thereby avoiding occurrence of a situation that "when the UE receives the information for terminating retransmission sent by the network device due to retransmission performed by using the continuous transmission opportunity, the UE has completed all repeated transmission", thereby reducing useless transmission and saving power consumption. In addition, the retransmission based on the discontinuous transmission resource in the present disclosure may also match the time domain channel diversity in the NTN channel to ensure the communication quality.

Fig. 2 is a flowchart of another method for indicating physical channel repeat transmission according to an embodiment of the present disclosure, which is applied to a UE, and as shown in fig. 2, the method for indicating physical channel repeat transmission may include the following steps:

step 201, receiving a corresponding relationship between indication information and transmission resources sent by a network device through a first signaling.

In an embodiment of the present disclosure, the transmission resource may include at least one of:

the time interval between each repeated transmission opportunity;

the number of retransmissions transmitted at each retransmission opportunity;

And, in one embodiment of the disclosure, the transmission resource is non-contiguous in time.

Further, in an embodiment of the present disclosure, the first signaling may be RRC (Radio Resource Control) signaling, and the UE may receive a correspondence between indication information and transmission resources sent by the network device through the RRC signaling, where the different indication information corresponds to different transmission resources, and the indication information may be an index (index value) and/or a bit value. In an embodiment of the present disclosure, the bit number of the bit value may be Nbit (bit), and N is a positive integer.

Specifically, in an embodiment of the present disclosure, when the indication information is a bit value, the UE may receive a correspondence relationship between a transmission resource (e.g., a time interval between each repeated transmission opportunity) sent by the network device through RRC signaling and the bit value of the specific domain in the second signaling.

And, in an embodiment of the present disclosure, when the indication information is an index, the UE may first receive a Start and Length Indicator Value (SLIV) table sent by the network device through RRC signaling, where the SLIV table includes a corresponding relationship between the transmission resource and the indication information, for example, a certain column in the SLIV table may be used to indicate a time interval between each repeated transmission opportunity, and each row of the SLIV table corresponds to an index.

Step 202, receiving indication information sent by the network device through the second signaling.

In an embodiment of the present disclosure, the second signaling may be DCI signaling.

Specifically, in an embodiment of the present disclosure, when the UE receives the corresponding relationship between the bit value sent by the network device through the first signaling and the transmission resource (e.g., the time interval between each transmission repetition opportunity) according to step 201a, the indication information in this step may be the bit value of the specific domain carried in the second signaling, and then the UE may determine the specific transmission resource, e.g., the time interval between each transmission repetition opportunity, according to the received bit value and the corresponding relationship.

And, in an embodiment of the present disclosure, when the UE receives, according to step 201a, the SLIV table sent by the network device through the first signaling, and the indication information in this step may be an index carried in the second signaling, the UE may determine the corresponding transmission resource based on the index and the SLIV table.

And, in an embodiment of the present disclosure, the method for the receiving network device to dynamically send the configuration information through RRC signaling and DCI signaling may be applied to a dynamically scheduled data channel.

Step 203, determining the corresponding transmission resource based on the corresponding relation of the first signaling and the indication information included in the second signaling.

Specifically, in an embodiment of the present disclosure, the UE may determine the corresponding transmission resource by using the correspondence between the indication information and the transmission resource sent by the network device through the first signaling and the indication information in the second signaling.

For example, in an embodiment of the present disclosure, assuming that the 5 th column in the SLIV table sent by the receiving network device through RRC signaling is used to indicate transmission resources, which respectively indicate the repeated transmission pattern information 1, the repeated transmission pattern information 2, the repeated transmission pattern information 3, the repeated transmission pattern information 4, and the repeated transmission pattern information 5, and index values corresponding to the repeated transmission pattern information 1, the repeated transmission pattern information 2, the repeated transmission pattern information 3, the repeated transmission pattern information 4, and the repeated transmission pattern information 5 are sequentially 2, 4, 6, 8, and 10, and assuming that the index value 4 is included in DCI signaling sent by the network device received by the UE, the repeated transmission pattern information 2 may be determined as a transmission resource based on the SLIV table and the index value 4.

And, in another embodiment of the present disclosure, it is assumed that the corresponding relationship between the bit value sent by the network device through the RRC signaling and the transmission resource is: a bit value of 00 corresponds to the repetitive transmission pattern information 1, a bit value of 01 corresponds to the repetitive transmission pattern information 2, a bit value of 10 corresponds to the repetitive transmission pattern information 3, and a bit value of 11 corresponds to the repetitive transmission pattern information 4. And assuming that the DCI signaling transmitted by the network device and received by the UE includes a bit value of 00. The repetitive transmission pattern information 1 is determined as a transmission resource based on the correspondence of the bit value to the transmission resource and the bit value of 00.

And step 204, determining a repeated transmission opportunity according to the transmission resource.

In an embodiment of the present disclosure, for a detailed description of step 203, reference may be made to related descriptions in the foregoing embodiments, and details of the embodiment of the present disclosure are not repeated herein.

In summary, in the method for indicating physical channel repeat transmission provided in the embodiment of the present disclosure, the UE may receive configuration information for repeat transmission sent by the network device, determine a transmission resource for repeat transmission according to the configuration information, where the transmission resource is discontinuous in time, and determine a repeat transmission timing according to the transmission resource. Therefore, in the embodiment of the present disclosure, the UE may perform repeated transmission by using a discontinuous transmission resource, that is, each transmission opportunity has a time interval, and based on this, after the UE performs retransmission at a certain transmission opportunity in the NTN system, if the network device finds that transmission can be terminated and sends information for terminating retransmission to the UE, the UE may not reach the next transmission opportunity when receiving the information for terminating retransmission, thereby avoiding occurrence of a situation that "when the UE receives the information for terminating retransmission sent by the network device due to retransmission performed by using the continuous transmission opportunity, the UE has completed all repeated transmission", thereby reducing useless transmission and saving power consumption. In addition, the retransmission based on the discontinuous transmission resource in the present disclosure may also match the time domain channel diversity in the NTN channel to ensure the communication quality.

Fig. 3a is a schematic flowchart of another method for indicating physical channel repeat transmission provided in the embodiment of the present disclosure, which is applied to a UE, and as shown in fig. 3a, the method for indicating physical channel repeat transmission may include the following steps:

step 301a, receiving configuration information for repeated transmission sent by a network device, where the configuration information includes transmission resources specifically used for repeated transmission.

the time interval between each repeated transmission opportunity;

the number of retransmissions transmitted at each retransmission opportunity;

And, in an embodiment of the present disclosure, the transmission resources included in the configuration information are discontinuous in time.

That is, in one embodiment of the present disclosure, the configuration information may include specific transmission resources, for example, may include the total number of direct repeat transmissions and the time interval between each repeat transmission opportunity.

Further, in an embodiment of the present disclosure, the method for receiving configuration information for repeated transmission sent by a network device may include: and receiving the configuration information sent by the network equipment through the third signaling.

And, in an embodiment of the present disclosure, the third signaling may be RRC signaling, and the receiving of the configuration information sent by the network device through the third signaling may include any one of:

receiving configuration information sent by a network device through RRC signaling for configuring SPS (Semi-Persistent Scheduling) (i.e., directly configuring transmission resources in configuring SPS);

receiving configuration information sent by a network device through RRC signaling for configuring a PUSCH configured grant type 1 (physical uplink shared channel configuration grant type) (i.e. directly configuring transmission resources in a configuration for configuring the PUSCH configured grant type 1);

receiving indication information sent by the network equipment through RRC signaling for configuring the physical channel (namely, directly configuring transmission resources in the configuration for configuring the physical channel).

And, in another embodiment of the present disclosure, the method for receiving configuration information for repeated transmission sent by a network device may include: and receiving the configuration information sent by the network equipment through the fourth signaling.

In an embodiment of the present disclosure, the fourth signaling may be DCI signaling, and the method for receiving the indication information sent by the network device through the fourth signaling may include any one of the following:

receiving configuration information sent by a network device through DCI signaling for activating SPS;

receiving information transmitted by the network device through DCI signaling for activating PUSCH configured grant type 2.

Step 302a, determining transmission resources for repeated transmission according to the configuration information.

In an embodiment of the present disclosure, since the configuration information received in step 301a includes a transmission resource specifically used for repeated transmission, this step may directly determine the content included in the configuration information as the transmission resource.

Step 303a, determining a repeat transmission opportunity according to the transmission resource.

In an embodiment of the present disclosure, for a detailed description of step 303a, reference may be made to related descriptions in the above embodiments, and details of the embodiment of the present disclosure are not repeated herein.

Fig. 3b is a flowchart illustrating a further method for indicating physical channel repeat transmission according to an embodiment of the present disclosure, which is applied to a UE, and as shown in fig. 3b, the method for indicating physical channel repeat transmission may include the following steps:

and step 301b, receiving configuration information which is sent by the network equipment and used for repeated transmission. Wherein, the transmission resource included in the configuration information is the total number of repeated transmissions.

Step 302b, determining transmission resources for repeated transmission according to predefined information and configuration information.

Only the total number of repeated transmissions can be determined in response to the configuration information in step 301b described above. Thus, other transmission resources may be determined based on predefined information.

Wherein, in one embodiment of the present disclosure, the predefined information may be used to determine at least one of:

the time interval between each repeated transmission opportunity;

the number of retransmissions transmitted at each retransmission opportunity;

the pattern information is repeatedly transmitted.

Based on this, in one embodiment of the present disclosure, the UE may determine transmission resources for the repeated transmission in conjunction with the configuration information based on predefined information.

For example, when the network device configures only the total number of repeated transmissions through the configuration information, the time interval between each repeated transmission opportunity and the number of repeated transmissions transmitted per repeated transmission opportunity may be determined based on predefined information, or the repeated transmission pattern information may be determined based on predefined information. Thus, the UE can determine all transmission resources required for the physical channel to repeat transmission based on the received configuration information and the predefined information.

Step 303b, determining a repeat transmission opportunity according to the transmission resource.

In an embodiment of the present disclosure, reference may be made to related descriptions in the above embodiment for detailed description of step 303b, and details of the embodiment of the present disclosure are not repeated herein.

step 301c, receiving a corresponding relationship between indication information and transmission resources sent by the network device through the first signaling.

Step 302c, receiving the indication information sent by the network device through the second signaling, where the transmission resource corresponding to the indication information carried in the configuration information (that is, the corresponding relationship in step 301c and the indication information in step 302 c) only includes the total number of times of repeated transmission.

Step 303c, determining transmission resources according to the predefined information and the configuration information.

Only the total number of repeated transmissions can be determined in response to the configuration information in step 302c described above. Thus, other transmission resources may be determined based on predefined information.

the time interval between each repeated transmission opportunity;

the number of retransmissions transmitted at each retransmission opportunity;

the pattern information is repeatedly transmitted.

For example, when the network device configures only the total number of repeated transmissions by the configuration information, the time interval between each repeated transmission opportunity and the number of repeated transmissions transmitted per repeated transmission opportunity may be determined based on predefined information, or the repeated transmission pattern information may be determined based on predefined information. Thus, the UE can determine all transmission resources required for the physical channel to repeat transmission based on the received configuration information and the predefined information.

And step 304c, determining the repeated transmission opportunity according to the transmission resource.

In an embodiment of the present disclosure, for a detailed description of step 304c, reference may be made to related descriptions in the above embodiments, and details of the embodiment of the present disclosure are not repeated herein.

And, in an embodiment of the present disclosure, the physical channel repeated transmission may include at least one of:

repeated transmission of PUSCH;

repeated transmission of PDSCH;
